Error While Creating a New Workspace

I am trying to create a workspace from /desk/build page (new button in lower side of the page). I fill up the form (as the image attached) and then I receive “Value too big”. After that, the page shows and edit version of the build workspace.

Is this the correct way to create a new workspace? Any recommendations for solving this issue.

I also have this error. Is there a solution for the latest installed system

also have the same problem. any help??
